Abstract

Abstract

Background
As an important part of klystrons, the characteristics of the resonant cavity have a decisive influence on the performance of klystrons. In the field of high-band klystrons, due to the limitation of processing technology and welding technology, the integrally processed rectangular resonant cavity is mostly used.
Purpose
The traditional integrally processed rectangular resonant cavity is prone to problems such as frequency deviation of the resonant cavity or even inoperability of the resonant cavity when frequency adjustment is performed.
Methods
Accordingly, this paper innovatively proposes a practical new frequency-modulation structure: a coupling diaphragm with slots cut into the resonator cavity walls and openings added.
Results
Simulation calculations validate that when this structure is applied to the rectangular resonant cavity, a large-scale frequency adjustment can be achieved, effectively compensating for the frequency deviation caused by the machining tolerance of parts.
Conclusions
During frequency tuning, applying external force deforms the diaphragm to increase cavity frequency, while enlarging the coupling aperture on the diaphragm lowers it. Moreover, the frequency adjustment operation becomes simple and rapid, significantly improving the research and development efficiency of the klystron, thus providing a new technical approach for the optimization and development of high-band klystrons.
